JAVA 语言的函数式编程扩展

  val foo: Array[String] = Array("1","2","3")
  if (foo.length == null) //  == 0 makes more sense, but still
    println("plante")     // this code leads to runtime crash
  else
    println("plante pas")

  def main(args: Array[String]) = {
    val in = new java.io.FileInputStream(args(0))

    var c = 0

    in.close

  println(new Object == 1)
  println(1 == (new Object))
